Das is difference of 2 perfect squares
remember
a^2-b^2=(a-b)(a+b)

so
25x^4=(5x^2)^2
16y^2=(4y^2)

(5x^2)^2-(4y)^2=(5x^2-4y)(5x+4y)
cannot be factored further

Answer:

(5x^{2} + 4y),(5x^{2} - 4y)

Step-by-step explanation:

Given  : 25x^{4} - 16y^{2}.

To find : What is the completely factored form .

Solution : We have given  25x^{4} - 16y^{2}.

We can write it as

(5x^{2})^{2} - (4y)^{2}

Using the identity a^{2} - b^{2} = (a+b) (a-b).

Here, a = (5x^{2}) , b = (4y).

Then  ,

(5x^{2})^{2} - (4y)^{2} = (5x^{2} + 4y)  , (5x^{2} - 4y)

Therefore, (5x^{2} + 4y),(5x^{2} - 4y)

Ms.Tao flies roundtrip twice yearly between Jacksonville and Los Angeles on business the distance between the two cites is 2,150
vlabodo [156]
2,150 estimated would be 2,000. Since she flies there and back multiply 2,000 by 2. Since she flies it twice multiply 4,000 by 2. Estimated: 8,000 miles. To find the exact miles Do the same thing but with 2,150: 2,150 times 2 = 4,300. 4,300 times 2 = 8,600. She flies exactly 8,600 miles per year :)
